Abstract

The information processing method includes: an evolved NodeB sending information of PRACH resources configured for a UE to the UE via a PDSCH indicated by a downlink control channel, and after receiving a random access preamble sequence sent from the UE, the evolved NodeB sending downlink control information and a Random Access Response (RAR), wherein the downlink control channel is an enhanced Physical Downlink Control Channel (ePDCCH); or, information carried by PBCH indicates that the downlink control channel is the ePDCCH or a physical downlink control channel; or, when the LTE system bandwidth is less than or equal to the reception bandwidth of the UE, the downlink control channel is a physical downlink control channel, and when the LTE system bandwidth is larger than the reception bandwidth of the UE, the downlink control channel is the ePDCCH.
